JE History
The origins of what we know today as JE Pistons can be traced back to 1912 and the Los Angeles foundry of William Jahns Sr. and his company W.H. Jahns. Employing the tagline, “Nothing but Pistons,” the W.H. Jahns company produced pistons and semi-finished pistons until 1948, when Jahns Sr. retired. Meanwhile, Jahns’ son, William “Uncle Bill” Jahns Jr., started and had been working on his company Jahns’ Racing Pistons since 1947. Shortly after, the business became Jahns’ Engineering Pistons, and was finally shortened to JE Pistons.
Through the following years, JE Pistons’ technology evolved, from mastering casting technology in the 60s to researching and implementing forging technology in the 70s. Numerical Controlled (NC) machines were introduced to manufacturing in the early 80s, which was quickly improved to the use of Computer Numerical Controlled (CNC) machines and a proprietary piston design and machining program in the mid-80s.

Seems like it'd be less work to shove a 350 4bbl in the car....
Can your high-performance engine benefit from gas ports? Discover how the different types of modern gas ports can improve piston ring sealing and combustion pressure management for optimal performance in your next build.

Great article!! I’ll chat with Eric for my next set.
Not new Smoky done them in the 60s, gassing the piston
Horizontal gas ports above top ring came after these. Early to Mid 70s era.
I'm sure they work great until the small gas ports carbine up which they will I guarantee then you're basically back to a typical piston setup !
Gas ported rings work nice also.
Question. 557" Ford, heavy Nitrous use. How many vertical ports and what size? Thanks Richard
It's clear most people don't read the articles. Those same people have all the answers...
Bullshit. Get a good set of gapless rings that don't create excess drag on yhe rings
It's called ring jacking. Not good!
JE = Junk Engineering! I got 2 sets of there ash trays on the shelf....no thanks
I need 4.560 bore with 3.76 stroke set for my procharged street engine
A very old concept that some companies said did nothing
Stick to what works
Not for street use! The extra pressure on the rings will wear the rings and the cylinder walls pre-maturely, eradicating durability! Reserve for race only. 🙂
I.ll be needing 10 in the near future. I.ll give u guys a call
